Abstract
Die Erfindung betrifft einen Synchronmotor mit permanentmagnetischer Felderregung, mit einer mehrphasigen Ankerwicklung (11) und einem die Ankerwicklung (11) an ein Spannungsnetz (10) anschließenden, mehrphasigen Umrichter (12), sowie mit einer Steuerlogik (14) zur Umrichtersteuerung. Zwecks Gewährleistung eines zuverlässigen Schutzes für den Umrichter und zur Motorstillsetzung bei allen möglichen Störfällen ist eine Schutzvorrichtung (20) vorgesehen, die eine elektronische Schalteranordnung (21) zum Kurzschließen der Wicklungsphasen der Ankerwicklung (11) und eine die Schalteranordnung (21) im Störungsfall ansteuernde Steuervorrichtung (22) aufweist The invention relates to a synchronous motor with permanent magnetic field excitation, comprising a polyphase armature winding (11) and a multi-phase converter (12) connecting the armature winding (11) to a voltage network (10) and to a control logic (14) for converter control. In order to ensure reliable protection for the inverter and engine quenching in all possible incidents a protective device (20) is provided which includes an electronic switch assembly (21) for short-circuiting the winding phases of the armature winding (11) and the switch arrangement (21) in the event of failure control device (22)
